During a training session observed by Hippolyta, Diana sparred against her fellow warriors, demonstrating her weapons expertise and defeating each of them swiftly. Her final opponent was Antiope herself. The two fought with all their might. Diana managed to disarm Antiope and looked toward her mother for approval. Antiope seized the opportunity to push Diana to the ground and pick up her sword, admonishing her for letting her her guard down. As Antiope slashed at her and forced her backwards, Diana instinctively brought her arms together to block the attack. She clashed her arm gauntlets together, resulting in her unleashing a powerful shock-wave that sent Antiope flying back and left all spectating Amazons there, including Diana herself, in complete shock.
Following Pérez, William Messner-Loebs took over as writer and Mike Deodato became the artist for the title. Messner-Loebs introduced Diana's Daxamite friend Julia in Wonder Woman vol. 2 #68 during the six-issue space arc. Messner-Loebs's most memorable contribution to the title was the introduction of the red-headed Amazon Artemis, who took over the mantle of Wonder Woman for a short time. He also included a subplot during his run in an attempt to further humanize Diana by having her work for a fictional fast food chain called "Taco Whiz".
By the end of the war, Diana began to lose faith in both humanity and herself after Ares opened her eyes to humanity's potential for evil. While she still believed in the power of love and compassion to change humanity for the better, Diana was left sobered and emotionally broken over certain events from the war, such as the use of Dr. Poison's gas to massacre the entire village of Veld, and Steve Trevor's self-sacrificing death. After witnessing a "century of horrors", Diana largely stepped away from heroics until she witnessed the seemingly unstoppable Doomsday wreck havoc; ultimately joining in to battle him alongside Batman and Superman. After witnessing Superman's own sacrifice to stop the monster, however, Diana turned once again towards heroics; demonstrating not only her underlying belief in her own core values, but also in the positive effect true heroes can have on the world.
The "Diana Prince" identity has been part of Wonder Woman's history since her comics debut in 1941. In the early Golden Age stories, Wonder Woman served as a military secretary during World War II, using Prince as her cover. Later occupations Wonder Woman performed as Prince included translator at the United Nations, Air Force captain and ambassador, and in the '70s TV series, Lynda Carter's Wonder Woman used Prince to serve as an agent of the Inter-Agency Defense Command. In the DC Extended Universe, Prince works as curator for the Department of Antiquities at the extremely prestigious Louvre Museum and is held in very high esteem by the curator of the Gotham City Museum of Antiquities. Her tremendously long life span, accumulation of immense amount of knowledge and exceptional perceptiveness makes Diana Prince the wisest and most emotionally-intelligent member of the Justice League.
In an October 25, 1940, interview with the Family Circle magazine, William Moulton Marston discussed the unfulfilled potential of the comic book medium. This article caught the attention of comics publisher Max Gaines, who hired Marston as an educational consultant for National Periodicals and All-American Publications, two of the companies that would merge to form DC Comics. At that time, Marston wanted to create his own new superhero; Marston's wife and fellow psychologist Elizabeth suggested to him that it should be a woman:
A few decades later, second-wave feminist Gloria Steinem's Ms. Magazine debuted in 1972 with an image of Wonder Woman on the cover. Historian Tim Hanley suggests that this move shifted "the focus away from female superiority to sisterhood and equality, essentially making her a mascot of the women's movement". This perception shifted over the years, as demonstrated in December 2016 when the United Nations decided to drop the title of "honorary ambassador for the empowerment of women and girls" which it had given to the comic book character Wonder Woman a few months prior, in a ceremony attended by the actors who had portrayed her (Lynda Carter and Gal Gadot). The title was eliminated in response to a petition signed by 44,000 people which argued that Wonder Woman undermines female empowerment due to her costume, described as a "shimmery, thigh-baring bodysuit with an American flag motif and knee-high boots". The petition stated that "it is alarming that the United Nations would consider using a character with an overtly sexualised image at a time when the headline news in United States and the world is the objectification of women and girls". Wonder Woman director Patty Jenkins responded to both the petition and to the U.N.'s decision by stating that she thinks "that that's sexist. I think it's sexist to say you can't have both. I have to ask myself what I would apply to any other superhero".
The First Born imprisoned Wonder Woman in what remained of Olympus and ordered his forces to attack Themyscira. As they watched the confrontation, the First Born offered her a place in his goals of conquest, but she steadfastly refused, causing him to thrust a spike into her side. As Diana lied mortally wounded, Eris dragged her to Themyscira, for she wanted Diana to see her home destroyed and humiliate her. Recovering her strength, Wonder Woman punched Eris down and took Zola and Zeke to Olympus. Her plan was to place Zeke on the throne, so that he could be the new king of Olympus and end the bloodshed, but before she could, Poseidon revealed his presence.
As Themyscira's emissary to Man's World, Diana has made it her duty to lead by example, even if the differences between her birthplace and new home sometimes present hurdles for her to jump. She has come to represent the possibility and potential of life without war, hate or violence, and she is a beacon of hope to all who find themselves in need. She stands as an equal among the most powerful Super Heroes, with a sense of purpose to protect the world from injustice in all forms.
The success of the superhero television series Supergirl informed the marketing and promotion strategy used for Wonder Woman. According to Time Warner chief marketing officer Kristen O'Hara, they wanted to approach the Wonder Woman marketing campaign in a light manner, similar to how they did with Supergirl. O'Hara elaborated that the modest campaign route they took for Supergirl aided in establishing a large central fanbase among women well in advance of the series, which reportedly generated 5 million female superhero fans in one week. They were then able to model over time, and grow that audience leading up to the 15-months-later release of Wonder Woman. Though neither the film nor the series are aimed exclusively at women, the latter's campaign gave them their first opportunity to begin collecting data about female superhero fans. In May 2017, a promo for Wonder Woman was released during the season finale of Supergirl, featuring a remix of the song "These Boots Are Made for Walkin'" and Supergirl (Melissa Benoist) wearing Wonder Woman's boots. The promo included an appearance by Lynda Carter, star of the 1970s Wonder Woman, who plays the American president on Supergirl.
Alfred informs Bruce that people are in danger, which Batman tells Flash that he needs to save the civilians. Diana and Arthur try to keep Steppenwolf away from Cyborg by using the Lasso of Hestia to pull him down, then Steppenwolf attacked them both before he knocks Arthur into a wall breaking the ceiling before Diana saves him. Cyborg tries to keep Steppenwolf away from him, but fails which leads with Steppenwolf pulling off one of his legs.
Following Crisis on Infinite Earths, Wonder Woman was rebooted in 1987, by writer Greg Potter, who previously created the Jemm, Son of Saturn series for DC, was hired to rework the character. He spent several months working with editor Janice Race on new concepts, before being joined by writer/artist George Pérez. Inspired by John Byrne and Frank Miller's work on refashioning Superman and Batman, Pérez came in as the plotter and penciler of Wonder Woman. Potter dropped out of writing the series after issue #2, and Pérez became the sole plotter. Initially, Len Wein replaced Potter but Pérez took on the scripting as of issue #18. Mindy Newell would return to the title as scripter with issue #36 (November 1989). Pérez produced 62 issues of the rebooted title. His relaunch of the character was a critical and sales success.
The American theme of Diana's costume was explained by Pérez in the Challenge of the Gods storyline in which Diana engaged in a series of trials arranged by Zeus as punishment for refusing his advances. Diana met the spirit of Steve Trevor's mother, Diana Trevor, who was clad in armor identical to her own. Trevor revealed that during World War II she had crashed on Themyscira while on duty as a U.S. Army pilot. She blundered into an Amazon battle against Cottus, a multi-armed demon, at the portal to the underworld. Trevor was drawn into the battle, although she was armed only with her side arm. She wounded the beast before suffering a mortal blow, allowing the Amazons to reseal the portal.
Before Steppenwolf could kill Cyborg, Superman comes and saves him, by easily overpowering the New God. Bruce tells Superman he needs to buy Cyborg some time to separate the Mother Boxes and to help civilians, Superman catches up with Barry, saying he got the ones on the right. After subduing Steppenwolf again, Victor calls Superman for help with the Mother Boxes. Steppenwolf is not down yet and tries to attack, but Superman freezes Steppenwolf's Axe and Diana breaks it with her Sword, which finally leads to Steppenwolf realizing he has been defeated and is overwhelmed with fear for the first time. He is attacked by his own Parademons before he returns back to Apokolips.
After the release of the 2017 film Wonder Woman, many bloggers noted what they felt made Wonder Woman a feminist icon in the film. Zoe Williams for The Guardian said, "Yes, she is sort of naked a lot of the time, but this isn't objectification so much as a cultural reset: having thighs, actual thighs you can kick things with, not thighs that look like arms, is a feminist act. The whole Diana myth, women safeguarding the world from male violence not with nurture but with better violence, is a feminist act. Casting Robin Wright as Wonder Woman's aunt, re-imagining the battle-axe as a battler with an axe, is a feminist act. A female German chemist trying to destroy humans (in the shape of Dr Poison, a proto-Mengele before Nazism existed) might be the most feminist act of all." Alyssa Rosenberg for The Washington Post said, "... None of these experiences crushed me, of course, but I do wonder what it might have been like if they hadn't happened.The power of Wonder Woman, and one of the things that gives Jenkins's adaptation of the character such a lift, is in the answer to that question. Diana Prince (Gal Gadot) doesn't have any idea what women and men are — or aren't — supposed to do. Even when she does encounter other people's ideas about gender roles, she doesn't automatically accept them, and she never lets anyone stop her. And the movie goes a step further and argues that it's not merely little girls all over the world who stand to gain if they can grow up free of the distorting influence of misogyny: a world like that would be liberating and wonderful for men in lots of ways, too." Emma Gray for HuffPost said, "When it comes to pop culture, we speak often about representation; the simple yet often unfulfilled idea that it matters to see someone like you fill a variety of imagined roles on screen. After awhile, these conversations almost begin to feel obvious. We know that it's good to see women and people of color and disabled people and trans people and queer people in the same numbers and variety of roles that white, cisgender, straight men have long been afforded. But what these discussions often lose is the emotional impact of finally seeing something you may have never even realized you were missing. For many women viewers, "Wonder Woman" filled a hole they didn't know they had." 
In one episode, a newspaper editor named Brown, desperate to discover Wonder Woman’s past, assigns a team of reporters to chase her down; she easily escapes them. Brown, gone half mad, is committed to a hospital. Wonder Woman disguises herself as a nurse and brings him a scroll. “This parchment seems to be the history of that girl you call ‘Wonder Woman’!” she tells him. “A strange, veiled woman left it with me.” Brown leaps out of bed and races back to the city desk, where he cries out, parchment in hand, “Stop the presses! I’ve got the history of Wonder Woman!” But Wonder Woman’s secret history isn’t written on parchment. Instead, it lies buried in boxes and cabinets and drawers, in thousands of documents, housed in libraries, archives and collections spread all over the United States, including the private papers of creator Marston—papers that, before I saw them, had never before been seen by anyone outside of Marston’s family.
